DRIVING WITH THE ZF HP/VOITH DIWA.3 AUTOMATIC GEARBOX The ZF automatic gearbox has 4 or 5 forward speeds and 1 reverse gear. The Voith automatic gearbox has 3 or 4 forward speeds and 1 reverse speed. These gearboxes also have a built-in retarder. The automatic gearbox is electrically operated by selecting the required gear from a row of gear selector buttons on the instrument panel. Depending upon the specific application of the vehicle, the automatic gearbox offers the following gear selector positions: - 3 positions: DNR - 6 positions: 123 DNR Gear selector positions: R - Reverse: Reverse gear may only be engaged whilst the vehicle is stationary and the engine is idling. To engage position “R” from position “D”, “1,2,3”, the brake pedal must be depressed. Never engage reverse gear whilst driving forward. The reversing lamps light up whilst in the “R” position with the contact switched on. N - neutral (stationary) position: Only engage the neutral position when the speed of the vehicle is less than 5 km/h or when the vehicle is stationary. D - normal position whilst driving forwards. In this position the gearbox automatically changes UP and DOWN through all the forward speeds (depending upon the road speed and the position of the accelerator pedal). Under certain circumstances during driving it is better to temporarily engage one of the options described below. 1 - position for steep mountainous routes: This option is recommended for extreme height differences and steep inclines. The vehicle only drives in 1st gear. 2nd and 3rd gear remain blocked. The maximum engine operation is reached due to this. The speed regulating system cannot be used whilst in position 1. 2 - position for mountainous routes: This option is intended for long inclines and routes with steep hills. 1st and 2nd gears are changed up and down depending on the engine load and the driving speed. 3rd and 4th gears remain blocked. The engine brake operation is further increased due to this. 40 DRIVING
3 - position for hilly routes: 1st, 2nd and 3rd gears are changed up and down depending on the engine load and the driving speed. Kick-down A kick-down switch is fitted under the accelerator pedal. When fast acceleration is required, the accelerator pedal should be pushed down to its full extent. Depending upon the road speed, this will cause the gearbox to change down automatically to a lower forward speed. Changing up to the next gear will only occur once the maximum engine speed allowed has been reached. Starting The engine can only be started when position N is engaged. Operate the parking brake before starting. ZF Automatic gearbox: At temperatures below - 15°C start the engine and run the engine warm in position N for about 10 minutes at 1000 rpm before driving away. Driving away from rest With the vehicle stationary, the brakes applied and the engine idling, select the desired position (D = forward speed, or R = reverse), then wait for 1-2 seconds, release the brakes, depress the accelerator pedal and drive away. Do not accelerate whilst switching on and stationary. Note To prevent the bus from rolling backwards whilst on a slope, the accelerator should be depressed before the brake pedal/parking brake is released. Special note! If the vehicle does not drive away or the wrong option is selected: - Remove the foot from the accelerator; - Press the “N” key and then the desired option key. Should you unintentionally engage position N whilst the vehicle is in motion, you must again select position D in order to prevent damage to the drive line. The electronically controlled gear selector unit will then automatically select the forward speed that matches the road speed. Stopping The vehicle can always be brought to a stop regardless of the chosen gear. The electronic automatic gear always changes to 1st gear after stopping (depending on any fitted options such as Neutral at Stationary (NBS, EK-ab) etc.). Whilst stopping for a short period of time, for example at a traffic light, the gearbox can remain in option “D” or in the chosen gear. The engine may then only idle. Driving in reverse Change from “D” to “R” or vice versa: - Bring the vehicle to a stop and keep the brake pedal depressed; - Idle the engine; - Push in the neutral switch “N”. If the vehicle is equipped with a switch (39), then this switch should also be operated. - Select the required option. DRIVING 41
